mcdevito75 here, I've also riuned a number of Casio watches replaceing the battery, extra, extra care is needed, first remove the back cover screws, then you:ll have to remove another cover for the battery, after replaceing the battery the work begins, very carefully reverse the removal procedure, any un do pressure will cause the movement to break and the face of your watch will turn Black. Best with your casio is to let a watch repair shop change the battery, look for a small shop to save some money.

i think you have a dud, i would conatct casio directly.
this model is radio controlled so will always set it self to the correct local time , i can only think that the watch is switching off an on causing it to reset the date then when it picks up the signal it resets the time.

My Casio wave ceptor keep resetting itself like this when the bottom right (D button) is pressed. I need to make sure I reset the city code or before trying to receive as it defaults to Tokyo. Press & hold the top left (A button) and date changes to city code. Scrole through codes using right bottons.
Hope this helps.

There are different types of watches worn, from the simple, casual designs to the large, Swiss-made pieces of art for the elite. Regardless of the type, they all need routine care and maintenance to keep them running and looking good. One of the best long-term investments you can make in a watch is in battery replacement.

When it comes to watch battery replacement, the first step is to test the battery and ensure that it is the source of the problem. There are numerous watch and battery testers available that will allow you to test watch movement while it is closed.

Once you have determined that the battery is the problem, open the case. As you are proceeding with this process, confirm what kind of battery you have and the correct size replacement you will need. Take a note of the current battery number before you remove it. This will be helpful in case the batter slips out of the case and gets lost. For some batteries, you may need to reset the movement before they can function again.

When you have finished changing the battery, replace the back on the watch before putting it on again.

I had the same problem this week and after downloading and reading the operation guide, I found the "adjusting the home positions" procedure in page 2, I followed the instructions and now my Casio 4303 is up and running, I got the operation guide from: http://ftp.casio.co.jp/pub/world_manual/wat/en/qw4303.pdf (thanks to jeffw284 for the information).
I hope this helps to solve your problem.
Best regards.

You can align the analogue time with the digital time by pressing the mode button until you reach the hand setting position (HS) and then press one of the right hand buttons to change the hand position.

Take a look at http://www.stauer.com/pdf/17468.pdf
I see that this watch gets it's time signal from Boulder, Colorado so it will only work properly in North America. Perhaps they also do models for the European market - if so I would expect them to work in the same fashion so the manual should still be relevant.

mcdevito75 here, 1 of the buttons should say MODE, press this button and see the display blinking, NOW! press the set button for each function, after each function is set press MODE to move onto the next function, when all functions are set, press MODE again to see steady display.
